The run_thunkgen* helpers now parse generated source code and return its AST representation, so HasASTMatching helper calls don't each need to redundantly compile it themselves. This also ensures the generator output actually compiles in tests where we didn't explicitly check that before. This also allows printing the full AST of the generator output on test failures. This must be enabled manually by changing a variable in the ostream output operator for SourceWithAST.
